In 'Chrono Chums: Who's There?', players take on the role of a time-traveling detective who finds themselves entangled with a group of eccentric historical figures who are uncharacteristically aware of their own fictional existence. As they jump through various pivotal moments in history, players must unravel a quirky conspiracy that threatens the fabric of time itself. Form bonds with notable personalities, solve clever puzzles, and decide how your interactions will shape the timeline while evading the manipulative 'Time Wraiths' intent on keeping certain events intact. Each choice can lead to hilarious, dramatic, or absurd outcomes that question the very nature of friendship, loyalty, and absurdity in history.
